Mousam River

East St. Louis Creek during summer high flow (June 2007)
A step-pool reach on East St. Louis Creek in Fraser Experimental Forest, Colorado. Note that steps, boulders, and wood are all submerged during high flow.

East St. Louis Low Flow

East St. Louis Creek during summer low flow (August 2007)
This is the same reach on East St. Louis Creek, but during the low flow period. Note how the water has to be diverted around boulders and has much further to fall over steps.

Winter Park, stream on ski slope

West Willow Creek on the Copper Mountain Ski Slope in the White River National Forest, Colorado
Vegetation was found to be an important factor for increasing stability of streams on ski slopes.
